Name:_________________________________________________
For this prelab exercise, please review the Labs #11 and #12 in your lab manual, then answer the following questions:
Lab #11: Stream Processes
The entire land area drained by a stream drainage system is called a _____________________ ____________________ (2 words).
The linear boundaries that separate one drainage basin from another are called _____________________ ____________________ (2 words).
What is the mathematical formula for stream gradient (slope of the stream bed)?
In general, how does stream gradient change as one moves downstream?
Compare Figures 11.1B and 11.1C. What are some of the differences between meandering and braided streams?
